Effective Student Assistance in Virtual Reality Based Intelligent Tutoring Systems

The joint use of virtual reality (VR) and intelligent tutoring systems (ITSs) benefits them qualitatively, since their application scope and interaction possibilities are increased. The educational improvement implies the adaptation of the tutoring processes to the new environment, including exploiting many different and, sometimes, novel information types. One of the processes affected is that of the student assistance, which finds in 3D virtual environments new channels to operate. In this paper, the assistance capabilities of these systems are categorized, and the particular assistant system of the MAEVIF platform is described.
